GAS-BURNING ATTACHMENT FOR COAL-RANGES.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed August 21, 1914. Serial No. 857,825.

To all whom t may concern Be it known that I, AUGUSTUS F. HARTER, a citizen of the United States, residing at Chicago, county of Cook and State of Illinois, have invented a certain new and useful Improvement inv Gas-Burning Attachments for Coal-Rangegand declare the following to be a full, clear, and exact description ofv my .invention is characterized will herein` after be pointed out .with particularity in the claims; but, for a full understanding of my invention and of its object and advantages, reference may be had to the following detail description taken in connection with the accompany drawings, wherein:

Figure 1 is a top plan view of an ordinary coal range equipped in accordance with the present invention, parts being broken away; Fig. 2 is a section taken on line 2--2 of Fig. 1; Fig. 3 is a section taken on line 3-3 of Fig, 2; Fig. 4- is a section taken on line 4.-1 of Fig. 1, the burner stem being shown in elevation; Fig. 5 is a section taken on line 1-4 of Fig. 1, the burner stem being shown in elevation, illustrating a dierent type of burner from that appearing in Fig. 4; Fig. 6 is a top plan View, on a larger scale, of the omitted; Fig. 7 is a view similar to Fig. 6 with detachable part's'removed; Fig. 8 is a section on line 8-8 of Fig. 6; and Fig. 9 isl a section on line 9-9 Aof Fig. 7.

Referring to the drawings, 1 represents the top of an ordinary'siX-hole coal range. The two holes over the re pot and the two rear holes are'not changed in any way and are used in cookingwith a coal fire. Instead of the iisual front holes, I employ a detachfastened a pan comprising two bowl-like portions, 3 and 4, separated by a section having the shape of an ordinary center the front half of which is stationary. The rear half, 5, of this section is made detachable and, when lifted, leaves the rear halves of the bowls connected by a horizontal web, 6, lying considerably below the rims of the bowls. The center device, 5, inthe arrangement shown, is a casting of approximately V-shape having a blunt apex and sides concaved to conform to the curvature of the interior of the bowls and its depth is such that when it rests on the horizontal web, 6, it forms in effect the inner rear corners of the two bowls'and extends to about the plane of the top of the bowls; thus completing the two bowls. Between the rear edge of the member, 6, and the bottom of the plate, 2, is an opening, 7 which is closed by the member, 5, when the latter is in place. It will thus be seen that the member 5 forms the partition between the rear halves of the bowls and constitutes a portion of the wall of each bowl; at the same time `forming a closure between the bowls and the main draft passage in the upper portion ofthe stove. The front of each bowl terminates in a trough-like neck, 9. The pan fits tightly against the underside of the plate, 2,'so that the only openings through the joint between these two members are the opening, 7, and the openings formed by the troughs, 9. The plate, 2, is provided with a detachable center, 10, including the detachable rear half, 5, thereof, adapted to overlie the center between the'bowls and form over each bowl a round stove hole,f11.

The front wall, 12, of the range has openings, 13, each registering with the end of one of the troughs, 9, when the parts are assembled. A gas supply pipe, 14, is supported in front of the range and has a valved branch pipe, 15, in proximity to each ofthe holes, 13. Detachable burners, 16, are

- the stove holes.

The bowls 3 and 4 are shallow enough to insure a considerable clearance between the bottom thereof and the top wall, 1S, of the oven, thus preventing the draft passage, 19, above the oven from being completely shut off at any point when the gas burning appliance is placed on the range and permitting the oven to be properly heated from a coal fire, at such times. In other words, the gasburning appliance need not be removed in order to make it possible to heat the oven properly from a coal or wood fire.

Vhen the detachable center member, 5., is in place, communication between the bowls and the draft passage, 19, is cut off and, instead of using stove lids for the holes, 11, suitable grids, 20, such as are employed on gas stoves, may be used without danger that the combustion gases from the coal fire will enter the room through the gas burning attachment while gas is being burned. `Where the quality of the gas is such that the combustion gases are objectionable and should be carried away by the flue, the center section, 5, s removed, connecting the bowls to the draft passage, 19, above the oven, and ordinary stove lids or covers are placed on the stove holes, 11, over the burners.

The plate, 2, with its pan may be lifted olf the range and be carried to a suitable point, such as a sink in a kitchen, to be washed, so that they may easily be kept clean. When it is desired to remove the gasburning appliances and burn coal, the plate, 2, is replaced by suitable stove top members and the openings, 13, are closed by suitable doors or covers, 22.

In order to provide an increased number of gas burners, I have placed at one end of the range an extension, 25, which forms a continuation of the top of the range. The extension is in the form of a box having openings, 26 and 27, in the front and rear ends, two stove holes, 28, in the top, and an opening, 29, through the adjacent wall of the main portion of the range. whereby the interior of the extension is placed in communication with the draft passage, 19. A damper, 31, controls the opening, 29. Within the extension are two detachable transverse bars, 32 and 33, each lying beneath one of Each bar has therein a hole, 34, adapted to receive the lower end of a leg, 35, on a suitable burner, 36 or 37. The stems of the burners extend forwardly, side by side, and pass through the opening, 26, in the front of the extension into proximity to valved branches on pipe, 14. `Each burner is provided with two legs, one of which is adapted to enter the hole, 34, in one ofthe supporting bars while the other rests upon the bar. The stove holes may be covered by l means of grids, 38, or by means of stove lids or covers, 39; the damper, 31, being opened when lids or covers are employed and allowing the combustion gases to escape through the draft passage and chimney.

Where stove lids or covers are used, it may be advisable to raise the burners so as to bring them close to the lids or covers. This may be accomplished by making some burners, as indicated at 40 in Fig. 5, with comparatively long legs, 41. This permits the burners to be brought close to the top in the extension and also in the bowls, 3 and 4, which are provided with bosses, 42, and sockets, 43, for the reception of the legs of the burners; one leg of a burner resting on one of the bosses and the other resting in the corresponding socket. In the bottom of the extension is a drip pan, 45, having a handle, 46, projecting through an opening, 47, in the front wall of the extension; the opening being large enough to permit the withdrawal of the drip pan therethrough.

The top plate of the extension, the burners, the supporting bars and the drip pan may all be removed at will for cleaning purposes, so that all of the gas burning appliances may be kept free of dirt and grease.

While I haveillustrated and described in detail only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the denitions of my invention constituting the appended claims.

I claim: l

1. An attachment for a coal range com- ,J prising a plate, a detachable center forming with the plate two stove holes, a member secured to the under side of said plate and comprising two connected burner receiving bowls, there being an opening between said plate and said member at the rear of the plate and between the bowls, and a detachable center device arranged on said member for closing said opening.

2. An attachment for a coal range comprising a plate, a member secured to the under side of said plate comprising two bowls separated by a center and engaging said plate at their upper edges, the rear half of said center being removable for the purpose of placing the bowls communication with the draft passage when the attachment is on a range, and a removable center in said plate forming with the plate a stove hole above each bowl. p

8. An attachment for a coal range comprising a plate, two bowls arranged beneath said plate, the inner rear portions of the bowls being cut away to permit communication between the interior of the bowls and the surrounding space beneath said plate,

5 prising a plate, two bowls arranged beneath said plate, the inner rear portions of the bowls being out away to permit communication between the interior of the bowls and the surrounding space beneath said plate, a
